[svn-r10627] Purpose:
Feature - libtool shared library versioning
Description:
Libtool provides a mechanism for different versions of the same shared
library to be distinguished. Now this is applied to HDF5 when it is
built as a shared library.
Solution:
The version number is stored in config/lt_vers.am, and included in
src/Makefile.am.
This number will be automatically updated by bin/h5vers; developers
only need to update it when they change the API.
*** IMPORTANT ***
Any time the API changes, the version number in config/lt_vers.am must
be updated!
Platforms tested:
mir, eirene, verbena, modi4
Misc. update:
